IMPROVEMENT IN GALVANIC BATTERES.

Specification forming part of Letters Patent No. 178,215, dated May 30, 1876; application led lJanuary 23, 1875..

To all whom 'it may concern:

Be it known that I, JOHN E. WATSON, of Louisville, in the county of Jefferson and State ot' Kentucky, have invented a 'new and valuable Improvement in Voltaic Batteries; and I do hereby declare that the following4 is a full, clear, and .exact description of the construction and operation of the same, reference heilig had to the annexed drawings, making a part of this specitication, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of a vertical central section ot' my device, and Fig. 2 is a detail View.

y This invention has relation to voltaic batteries; and my object is to make a battery which is not subject to local action, and which will not require frequent attention.

The nature ot' my invention consists in a funnelshaped chamber, which is made ot' lead,and designed for containing the sulphate of copper, and which is surrounded by a zinc cylinder suspended from the cover of the battery-jar, as will be better understood from the following description.

In the annexed drawing, A designates a glass jar ot' any suitable size and Shape, which is provided with a wooden cover,B. C designates a funnel, consisting of the conical portion c, thickly perforated, and the cylindrical neck or tube b. JThis funnel C is made of lead,

. and the external surface otits tube b is coated with shellac to prevent the zinc or lead salt adhering to it. y The bottom ot' the cone a tits snugly upon the bottom ot' thejar A, and the upper end of the cylindrical tube b passes through the cover B, and may beA provided with a stopple. .The funnel is attached to the cover B by ,means of a copper strip, c, which forms an electrical communication with a binding-post, d. G designates a' cylinder of zinc, which Surrounds the upper portion of the funnel (l, and which is suspended from Y the cover B bymeans of rods g, toone of which the zinc-pole wire of the battery is suitably secured. The battery is preparedvfor action by charging the funnel C with sulphate ot' copper, and nearly filling the jar A with a solution ot' Sulphate of zinc.

To prepare the battery for action, place the funnel C in the jar, and ll through the tube of this funnel with sulphate ot' copper. Then make a solution ot' sulphate of zinc-Say onequarter of a pound, and two ounces ot' the acetate of lead, in sufcient Water to cover the zinc. This solution is introduced into the jar, and instant action takes place. p

The function ofthe acetate of lead is important in keeping the metallic surface ofthe lead funnel in condition to receive the deposit of metallic copper, with which it will, theref'ore, become coated, and will serve as the copper pole of the battery.

What l claim as my invention, and desire to secure by Letters Patent, is V l. In a voltaic battery, the inverted lead funnel C, perforated through the conical portion, as shown, in combination with the copper strip c, and arranged in connection with the jar A, zinc pole, and cover B, substantially as Specified.

2. A battery solution formed of zinc sulphate, lead acetate, and water, adapted for use in connection with sulphate of copper,

metallic lead, and metallic zine, substantially as specified.

3. A battery consisting of thejar A, lead funnel O, zinc G, sulphate ot' copper, and solution of Sulphate of zinc and acetate ot' lead, combined and operatin g substantially as speci ed.

In testimony that I cla-im the above I have hereunto subscribed my name in the presence of two witnesses.

JOHN EDWARD WATSON.
